Michał Winiarski 2de0147d77 drm/i915/pmu: Avoid using globals for PMU events 
Attempting to bind / unbind module from devices where we have both
integrated and discreete GPU handled by i915, will cause us to try and
double free the global state, hitting null ptr deref in free_event_attributes.

Let's move it to i915_pmu.
